One doctor I saw had a sign in his office saying he charged $35 to fill out disability paperwork.

I'm in the medical field and have to fill out disability, FMLA, etc. all the time. It is very time consuming and I usually find myself having to stay after hours to do it or come in early to get it done uninterrupted. The problem is there is no way for a physician to bill for paperwork. The forms can be quite time consuming. I don't have an issue with a doctor charging to fill out the form. I do think it is a problem if they refuse all together to fill it out.
